License Overview

This page describes how licensing works in a Weka system cluster.

License Metrics

A Weka system license measures usage at the cluster level and contains the following properties:

  1. Cluster GUID (created at the time of installation)

  2. Expiry date

  3. Raw or usable hot-tier (SSD) capacity

  4. Object store capacity

When applied, the cluster verifies that the license is valid by comparing these properties and actual cluster usage.

To be able to start-io in a newly configured cluster, a valid license must be set (either a classic or a PAYG license).

Cluster Licensing Status

To view the cluster licensing status, run the weka status command:

# weka status
Weka v3.1.7.2 (CLI build 2.5.3)
...
       license: OK, valid thru 2018-07-31T07:14:05Z
...

In the example status above, it is possible to see that the cluster has a valid license which is due to expire on July 31st 2018. If the cluster does not have a valid license, the licensing status will appear as follows:

The system includes cluster alerts which also indicate if the cluster does not have an assigned license. Cluster alerts can be viewed by running the weka alerts command:

Obtaining a License

There are two ways to obtain a license for your cluster:

  1. Classic Licensing: In this method, payment is for a predetermined period of time, e.g., 1 year. See Classic Licensing for information more about this method.

  2. Pay-As-You-Go (PAYG) Licensing: In this method, payment is according to hourly usage. See Pay As You Go for more information about this method.
